Additional informations

HP70 mole is designed for hand installation of plastic pipes up to Ø75mm. 

Great merit of ths mole is high accuracy and low weight - 28kg. that's why HP70 is very handy and comfortable to work with.

Main purpose of the device is piercing holes for PE pipes installation up to Ø50mm . Tool works fine with Ø100mm expander in the second operation which allows Ø75mm pipes to be installed. Expanding primarily pierced hole to 100mm or more is dedicated to bigger moles.

Reverse mode is switched on by pulling the air supply hose. Easy and safe switching to reverse mode allows efficient piercing and also allows reverse the mole in emergency situations. Very important factor is that switching reverse mode on doesn't require turning air supply hose which might be difficult. Sometimes it might not even be possible due to lack of stiffness of the air supply hose when mole is far deep in the ground from the entry pit.

This device can be used for Ø50mm steel pipes ramming.

Purchase of this model is recommended for the following range of works: 80% plastic pipes up to Ø50mm; 20% plastic pipes Ø63-75mm.
